Application filed April 8,

This invention relates to a signal for' motor'veh'icles, the general object of the invention being to provide a signal lamp with ,Shift lever is moved to reverse position.

rlhis invention also consists in certain other features of construction and in the combination and arrangement of the several i parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended clain'i.

In describing the invention in detail, reference Will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a diagrammatic view of the invention applied to an automobile having a transmission of' the sliding rod type.

Figure 2' is a similar view showing the inve'ntion applied to an 'automobile equipped with a reverse pedal. Figure 3 is a side elevation of the per se.

Figure 4 is a longitudinal vertical sectional view therethrough. I

Figure 5 is a transverse sectional View.

Figure 6 is a detail view of one `of the spring contacts. i

In these views 1 indicates a signal lamp which is placed 'at any desired position on the rear part of the motor vehicle. v This lamp is of substantially fan Shape so as to give a wide beam of light. The bulb in this lamp is electrically connected with any suitable source of suppl as shown at 2, and a switch switch 3 is located in the circuit to control ,v

the same. As shown this switch comprises a' cylinder 4 which has one end closed and the other end screw threaded to receive 'a screw threaded Cap ,5. spring contacts S are placed inthe cylinder, the terminals 'Z of which extend through the cylinder and are suitably insulated therefrom. rfhese 'terminale have the ends of the conductors suita-bly secured theretof A piston 8 is arranged in the cylinder, and includes a'disk of non-conducting material and a ring of conducting material is carried by these parts and projects beyond the same so to electrically connectthe two contacts A pair of converging o 1922.

together when the piston has been moved inwardly. The piston also includes a pair of washers formed of insulating material and one of said washers is recessed to accommodate thedisk in a manner to secure the same between said washers and so that the disk is insulated from a relativcly long rod 9 which passes through the cap 5 and has a washer 10 on its .outer end which forms a seat' for a spring 11 which has its other end bearing against a part` of the cap., The switch is so positioned. that the end of the rod 9 will be strucklby the projecting end of 'the sliding rod 12 of the transmission means When the shift lever 13 ismoved into reverse position. When the lever is in this reverse position the part 12 will engage the end of the rod 9 and thus force the same inwardlyv againstthe action of the spring 11 alndso place the piston in engagement with t ie cuit through the switch and permitting: currentgto pass to the lamp, As soon as the shift lever is moved to neutral or any other position besides reverse,' the rod will be forced outwardly by the spring and thus move the piston out of engagement with the contacts and thus break the clrcuit to the lamp;

It will be seen that the switch can be used on Vall types of cars, and with all types of transmissions. When it is used on the Ford type the rod- 9 is placed where it will be pushedv inwardly by the reverse pedal so that it is simply a matter of .properly positioning` the switch to make it op-erable on any type of car or transmission.

It is thought from the foregoing description that the advantages and novel features of the' invention Will be readilv apparent. e desire it to be understoo. z that we may make changes in the construction and in the vcombination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What we claim is A switch of the character described comspring contacts, thus completing the cirprising a. cylinder, .a .pair of converging contacts fixed attheir remote ends in the cylin- 'der and being insulated thercfrom, a cap for one end of'said cylinder, a r-elatively long rod passing through said cap and having one end terminating in said cylinder, a piston secured to the last nientioned end of saidrod'and including a pair of washers of insulating material, a ;disk of conductng verging spring contacts for a w'iping engagw` surrounding the ment therewith, a spring rod for normally holding the disk out of engagement With converging contacts, .and the onter end of said rod being adapted to 10 lie in the path of'a movable part of an auto- Lee/'2,541 p mobile transmission in a manner whereby, said part is adapted to move said rod against the tenson of said spring to provide the wiping engagement of the disk With the eontacts.

In testimony whereo We afiix our signatures.
